Left by his mother upon her death in the care of Ben and Sarah Walters, Blue Fox must accept he is alone among people he doesn't know or trust. The years spent with Ben and Sarah are tumultuous, full of harsh words and bitter disappointments. But when Blue meets George Hawkins, a bond of friendship beyond race is formed. After years of being nearly inseparable, George goes away to West Point to become the soldier of his dreams and Blue's world falls apart. When White Oaks, the ranch Blue has come to call home, is attacked several times by a ruthless, racist man, Blue is forced to decide his place in life. Realizing his surrogate parents, whom he has grown to love, could be hurt or killed because of the attacks aimed at him, he sets out to find his heritage among the Sioux. Locating the tribe who'd been with his mother, uncle and Sarah, he quickly learns acceptance among the Sioux will not come easily. The young warrior Wild Wolf holds an unknown, bitter hatred of Blue, making his life difficult. But Blue's road is set and he travels far among The People, counting coup, learning their ways, and finally, participating in the Sun Dance to pass into manhood. Faced with the choice of saving the life of his enemy, Blue rides to the aid of Wild Wolf, killing a Crow brave only seconds before the warrior would drive his tomahawk into Wild Wolf's back. Following a revealing explanation for his hatred, Wild Wolf and Blue become "brother-friends" a bond stronger than that of brothers of blood. During a raid on the Crow by the warriors of his village, Blue spots a white woman trying to escape into the woods. He takes her as captive, vowing someday she'll come to him willingly. But she hides a dark secret that keeps her from giving herself to Blue. And when the wall surrounding her heart finally crumbles, the world around them spirals out of control when the U.S. Cavalry raids their village. Everything is destroyed, leaving them to travel north to join Crazy Horse's band of Oglala with no food, extra clothing or blankets against temperatures dropping to below zero at night. Blue and Amy survive the journey, but when the army is discovered in the Valley of the Rosebud, their future with the Sioux becomes uncertain. Led by Crazy Horse, the Sioux, including Blue, meet and defeat the Bluecoats. Hoping for peace, the Indians move on and settle in the Valley of the Little Bighorn. But peace is not to be. Only a week following the defeat of the soldiers at the Rosebud the "Long Hair" Custer comes to the valley of the Little Bighorn where he and his men are outnumbered and killed. Blue flees the battle, his white blood warring with his red blood over the carnage, and discovers his boyhood friend, George. Desperate to save his life, he hides George and returns to the Indian camp to retrieve Amy. The time of the Indian is coming to a close. It is time to return to White Oaks. But the road home is blocked by Wild Wolf. Unable to accept Blue's departure with a white woman and a white man Blue claims to be his brother, the ensuing confrontation ends in disaster. This is a story of coming of age, of learning to deal with the hatred and inability of people to accept another human being for what they are. It is, finally, a story of understanding, acceptance and love.
